Water Monitoring and Flow Measurement Systems for Hydrology

by HydroVision GmbH     based in Kaufbeuren, GERMANY

In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants. A further important use of transit-time open channel flow meters is the transportation of water used for the supply of drinking water. Here the focus lies on detecting the flow rate of water loss at an early stage as it is sometimes difficult to detect small leakages.

Industrial solutions for cooling water contamination

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

Boiler Water Testing / Cooling Tower Water Testing

by Myron L Company     based in Carlsbad, CALIFORNIA (USA)

Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level can be determined by the Ryznar or Langlier indices and correlated to a conductivity or TDS range. Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8` of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

Flow & Energy Management Solutions for plant & machine

by Spire Metering Technology     based in Marlborough, MASSACHUSETTS (USA)

Spire Metering offers several solutions for leakage detection. The flowmeters are used to monitor cooling water in machining process. They are used also in liquid process control and leakage detection applications.
